Payment gateway in Magento 2

Magento 2 is growing rapidly. We will soon be building our client’s stores on the platform with extensions. I wanted to take an opportunity which will go over at a bit of higher level on how to implement payment gateway module of Magento 2.

We believe that payments have problems rooted in code. We obsessively seek out elegant abstractions and flexible integrations. We eliminate needless complexity and extraneous details so that you can get up and  easily move with our payment gateway in just a couple of minutes.

As you probably know that a lot of changes are made in Magento 2. The module setup and the code structure is not an exception here. Our Magento payment provider gateway is a mechanism that allows you to integrate your stores with payment service providers. As a result, you can create and handle transactions based on order details.

So, by the end of this small series of blog post you will be able to do the following, with ease:

  • Follow and use api which is located in the Magento payment module.
  • There is a Gateway API inside the module which has interfaces and some common implementations.
  • We have set of UI elements which have to be used to show your custom Payment method under Checkout payment step.

Let’s take a tour into the payment implementation process to get a small and clear view of this.

So when we are discussing about any particular method, the first thing which occurs in our mind is how to use the method in a shorter as well as faster way. Likewise, if the payment method (i.e. PayPal Pro or is built into Magento 2, or if there is an extension available then it’s as easy as installing the extension and plugging in the payment gateway credentials. Honestly, that can be easier to do than setting up complex coupons or shipping methods for Magento 2.

However, if you are trying to implement a payment gateway for a smaller payment processor that doesn’t have a Magento 2 gateway installed, then that is a much bigger task.

In that case, it’s going to be a lot of work, unless the smaller payment processor has an emulation mode that works just like, but you just need to enter in different credentials and end points.

We have vast opportunities for our customers to implement the payment processes. We can provide maximum amount of credit to our clients through the predefined admin module and if the Credit Limit is already given or provided then one of the contact person can use it in order to purchase the order which are getting placed with the use of Credit Limit payment method. After placing the order there will be a deduction in Credit Limit balance by order amount. I have a small example for this above mentioned process:

Suppose if the available balance and credit limit is say 8000 and amount of the order is 2000 then the credit limit would be the same as 8000 but the balance which is available in the account should be 6000.


When a customer gets registered by providing the credentials in Magento store and places an order for the products, then there is a way to reach into the payment section in Magento 2.1.2 module. Here is an easy way:

Go to Stores –>Configuration –>Sales –> Payment Methods –> Choose the payment method.

Under payment method section from the Basic Settings you can configure:     

  • Title –The title of the payment method
  • Sort Order –Modifying this will change the display order of the payment method if more than one are available.
  • Payment Action –Here you can choose between Authorization and Sale. If you choose Authorization, you will have to authorize the payments before they can be processed. With the Sale option, the customer will be charged immediately after they pay.
  • Display on Product Details Page – Setting this to Yes will allow the payment method to be visible on the details page of every product.

In our payment method section, you can choose various options for payment:

Our popular payment gateways are available in one of these ways:

  • PayPal Pro
  • net
  • Bank Transfer
  • Check/Money order

We have two configuration setup views to give an idea about how our payment Gateway process works in our admin module and in our front end Magento module:

This is our admin module configuration setup:

magento admin module configuration setup

This is our Magento front end Configuration setup for the payment gateway:

magento front end configuration setup

So in this blog we have covered most of the basic things that are required for payment module development. Payment gateways are extremely needed in order to place an order and if it the process occurs in an easier way then it should be time saving for the customer as well. However, our module is really simple. This is just a warmup to get you started. I hope it is useful and easy to read and understand.
